3.4 Front Panel Programming Conventions
•
When programming an amplitude in the Program Menu, Sequence Edit Menu,
or remotely over the GPIB, the Amplitude field is checked against the Function
(Waveform) field for positive or negative amplitude; that is, the function polarity is
used to validate the amplitude input value. For example, programming -100V
when a DC+ waveform is selected will result in an execution error.
The polarity check has the following rules:
•
Negative amplitudes cannot be input for positive functions.
•
Positive amplitudes cannot be input for negative functions.
•
If the amplitude of a phase is positive, selecting a negative polarity function
will set the amplitude to zero.
•
If the amplitude of a phase is negative, selecting a positive polarity function
will set the amplitude to zero.
•
Phases A, B, and C will be of the same frequency. A frequency change of any
phase will affect the output frequency of all phases. The frequency field is
available in all three programming screens as a convenience.
•
A sequence can be run on one, two, or all three phases. Two different
sequences cannot be run on two phases simultaneously.
•
A sequence setting will take priority over continuous settings.
